Description

Oblast technikyTechnical field

Vynález se týká tvarovacího zařízení pro balicí stroje, které vytvářejí z ohebného obalového laminátu trubicovitého tvaru jednotlivá balení. Tvarovací zařízení je tvořeno chlopněmi tvaru U, které na sebe párově přiléhají svými koncovými částmi a tím se vytváří pravoúhlý prostor se čtyřmi stěnami pro část laminátové trubice, která se právě mezi chlopněmi nachází.BACKGROUND OF THE INVENTION The present invention relates to a forming apparatus for packaging machines which form single packages of flexible tubular tubular shaped laminate. The molding device is formed by U-shaped flaps which abut against each other with their end portions, thereby creating a rectangular space with four walls for the portion of the laminate tube just between the flaps.

Dosavadní stav technikyBACKGROUND OF THE INVENTION

Při výrobě obalů pro kapalný obsah.jako je mléko, ovocné šťávy a podobně, se často užívá ohebného laminátu, tvořeného vrstvami papíru a plastických hmot. Ve známém typu balicích strojů se dodává obalový laminát ve formě pásu, z něhož stroj při jeho kontinuálním postupu postupně vytvoří trubici, která je plněna požadovaným obsahem, příčně zatavena a jednotlivá balení jsou potom oddělena v těsnící oblasti za vzniku jednotlivých kapalinotěsných balení. V souvislosti s příčným zatavením se trubicovitý materiál zpracovává také tak, že jeho v podstatě kruhový průřez je měněn na průřez se čtyřmi stěnami, s výhodou se stýkajícími v pravých úhlech. Toho se dosahuje páry spolupracujících chlopní tvaru U v příčném řezu, otáčivých z otevřené polohy do polohy, v níž chlopně společně uzavírají část laminátové trubice a dodávají jí požadovaný pravoúhlý tvar. Každý balicí stroj je vybaven alespoň dvěma páry takových chlopní, které kromě pohybu mezi otevřenou a uzavřenou polohou vykonávají ještě vratný pohyb podél trubice obalového materiálu, takže v sobě uzavírají vždy další část trubice obalového materiálu a posunují tento materiál směrem dolů.In the manufacture of containers for liquid contents such as milk, fruit juices and the like, a flexible laminate consisting of layers of paper and plastics is often used. In a known type of packaging machine, a wrapping laminate is supplied in the form of a belt, from which the machine gradually forms a tube that is filled with the desired contents, transversely sealed, and the packages are then separated in the sealing area to form individual liquid-tight packages. In connection with the transverse sealing, the tubular material is also processed such that its substantially circular cross-section is changed to a cross-section with four walls, preferably at right angles. This is achieved by a pair of cooperating U-shaped flaps in cross-section rotating from an open position to a position in which the flaps together close a portion of the laminate tube and impart to it a desired rectangular shape. Each wrapping machine is provided with at least two pairs of flaps which, in addition to the movement between the open and closed positions, also reciprocate along the packaging material tube, so that they always enclose another part of the packaging material tube and push it downwards.

Při výrobě uvedených obalů známým způsobem dochází u některých typů obalových laminátů k deformaci jejich sevřením nebo stlačením v okamžiku, kdy se chlopně otáčejí z otevřené do uzavřené polohy. V tomto okamžiku může dojít k zachycení materiálu mezi koncovými částmi těchto chlopní, čímž dochází na obalovém materiálu k tvorbě podélných ostrých hran a může také dojít k poškození vrstvy plastické hmoty, takže materiál ztrácí kapalinotěsnost. Tato závada je samozřejmě nežádoucí a při výrobě sterilních balení způsobuje také nebezpečí ztráty sterility vnitřního prostoru a riziko infekce obsahu.In the manufacture of said containers in a known manner, some types of packaging laminates are deformed by clamping or compressing them as the flaps rotate from the open to the closed position. At this point, the material may become trapped between the end portions of these flaps, thereby causing longitudinal sharp edges to form on the packaging material and may also damage the plastic layer, so that the material loses its liquid tightness. This defect is, of course, undesirable and also causes the risk of loss of sterility of the interior space and the risk of infection of the contents in the manufacture of sterile packages.

Bylo již vyvinuto mnoho snah k překonání tohoto problému, například povlečením vnitřního prostoru chlopní materiálem s nízkým koeficientem tření, aby obalový materiál snadněji vklouzl do vyhloubení chlopní a nedošlo k jeho zachycení a sevření mezi chlopněmi. Až dosud však ještě nebylo nalezeno zcela uspokojivé řešení tohoto problému.Many efforts have been made to overcome this problem, for example by coating the inner space of the flaps with a low friction coefficient material so that the wrapping material slips more easily into the recesses of the flaps and does not get caught and clamped between the flaps.

Příklad provedení vynálezuDETAILED DESCRIPTION OF THE INVENTION

Tvarovací zařízení podle vynálezu může být použito v různých typech známých balicích strojů, především však v balicím stroji, který je schematicky znázorněn na obr. 1. Tyto a podobné balicí stroje vyrábějí balení nebo kartony pro kapalný obsah, například mléko nebo ovocnou šťávu z ohebného obalového laminátu, který je tvořen nosnou vrstvou z vláknitého materiálu, obvykle papíru, který je na kterékoliv své straně opatřen povlakem kapalinotěsné vrstvy z termoplastického materiálu, s výhodou polyethylenu. Obalový laminát může obsahovat ještě další .vrstvy pro zlepšení plynotěsnosti nebo neprůhlednosti laminátu, například hliníkovou fólii. Obalový laminát 2 se přivádí do balicího stroje 1 ze zásobníku, obvykle ve tvaru válce 3, z něhož se odvíjí obalový laminátThe forming apparatus according to the invention can be used in various types of known packaging machines, in particular in the packaging machine shown schematically in FIG. 1. These and similar packaging machines produce packages or cartons for liquid contents such as milk or fruit juice from a flexible packaging machine. a laminate comprising a carrier layer of fibrous material, usually paper, which is coated on either side with a liquid-tight layer of a thermoplastic material, preferably polyethylene. The packaging laminate may comprise additional layers to improve the gas-tightness or opacity of the laminate, for example, an aluminum foil. The packaging laminate 2 is fed to the packaging machine 1 from a container, usually in the form of a cylinder 3, from which the packaging laminate is unwound.

-2CZ 279925 B6 přes vodicí válečky 4 vzhůru do horní části stroje, kde je materiál veden přes vodicí válec 5 v podstatě vertikálně směrem dolů do stroje. Na své cestě strojem je obalový laminát 2 tvarován pomocí skládacích pomůcek 6 postupné na trubici 7 tak, že podélné hrany pásu jsou přeloženy přes sebe a staveny za vzniku kapalinotěsného podélného sváru pomocí zatavovacího zařízení 8.. Potom je trubice 7 naplněna příslušným kapalným obsahem pomocí plnicí trubice 9, zasahující do otevřeného konce trubice 2 v podstatě vertikálně směrem dolů těsně nad tvarovacími nástroji 10, uloženými vně trubice 7. Tvarovací nástroje 10 jsou tvořeny chlopněmi 11, párově spolupracujícími tak, že obalový materiál se mění z trubice 7 v podstatě kruhového průřezu do tvaru se čtyřstranným nebo pravoúhlým průřezem hotových obalů 12. Po konečném složení, to znamená zahnutí rohů směrem dovnitř je balení hotovo a vystupuje z balicího stroje.Through the guide rollers 4 upwards to the top of the machine, the material is guided through the guide roller 5 substantially vertically downwards into the machine. On its way through the machine, the packaging laminate 2 is shaped by folding aids 6 sequentially onto the tube 7 such that the longitudinal edges of the strip are folded over each other and fused to form a liquid-tight longitudinal weld by means of a sealing device 8. a tube 9 extending into the open end of the tube 2 substantially vertically downwardly just above the forming tools 10 located outside the tube 7. The forming tools 10 are formed by flaps 11 cooperating in pairs such that the wrapping material changes from a tube 7 of substantially circular cross-section into 12. After the final folding, i.e. the folding of the corners inwards, the package is finished and exits the packaging machine.

Shora uvedený postup zpracování pásového obalového laminátu 2 na jednotlivá balení v podstatě tvaru rovnoběžnostěnu je znám, takže není zapotřebí jej blíže popisovat.The aforementioned process of processing the sheet laminate 2 into individual packages of substantially parallelepiped shape is known, so there is no need to describe it in detail.

Tvarovací nástroje 10 podle vynálezu jsou podrobněji znázorněny na obr. 2, kde je znázorněna trubice 2 obalového materiálu, získaná v balicím stroji, například shora uvedeného známého typu. Trubice 2 je znázorněna v částečném řezu, takže je zřejmé, jak plnicí trubice 9 zasahuje do trubice 2 a jak kapalný obsah 13 vytéká z výstupního otvoru plnicí trubice 9. Postupná změna tvaru trubice 2 z kruhového průřezu na průřez pravoúhlý je prováděna tvarovacími nástroji 10, které jsou tvořeny chlopněmi 11 na každé straně trubice 2, v párech, přivrácených k sobě navzájem. Jak je zřejmé z obr. 3, má každá z chlopní 11 v podstatě průřez U a je tvořena střední stěnou 14 a dvěma vzájemně rovnoběžnými koncovými částmi 15. Ve spodní části je každá chlopeň 11 opatřena krátkým hřídelem 16., uloženým v podstatě horizontálně a spojujícím každou chlopeň 11 se zatavovací čelistí 17. Zatavovací čelisti 17 jsou pohyblivě spojeny neznázorněnými pákami a dalším zařízením s rámem balicího stroje 1, takže při chodu stroje mohou být od sebe poněkud oddáleny a opět k sobě stisknuty ve v podstatě horizontální rovině a mimoto se mohou poněkud pohybovat směrem nahoru a dolů, což odpovídá polohám, znázorněným na obr. 2. Chlopně 11 jsou také otáčivé mezi dvěma různými polohami, a to otevřenou polohou, znázorněnou v horní části obr. 2 a uzavřenou nebo pracovní polohou, znázorněnou ve spodní části obr. 2. Tento pohyb je prováděn neznázorněnými pákami, které jsou připojeny k nálitkům 18 na každé straně chlopní 11. Upevnění obou zatavovacích čelistí 17 a chlopní 11 a jejich pohon při chodu stroje jsou známé postupy, které není nutno podrobněji popisovat a které již byly popsány například v EP 91 712.The forming tools 10 according to the invention are shown in more detail in FIG. 2, where a tube 2 of packaging material obtained in a packaging machine, for example of the aforementioned known type, is shown. The tube 2 is shown in partial cross-section, so that it is clear how the filling tube 9 projects into the tube 2, i.e. when the content liquid 13 flows out of the outlet opening of the filling tube 9. Successive change in shape of a tube 2 of circular cross-section to rectangular cross-section is performed by the shaping tool 10 which are formed by flaps 11 on each side of the tube 2, in pairs facing each other. As shown in FIG. 3, each of the flaps 11 has a substantially cross-section U and is formed by a central wall 14 and two mutually parallel end portions 15. At the bottom each flap 11 is provided with a short shaft 16 extending substantially horizontally and connecting each flap 11 with the sealing jaw 17. The sealing jaws 17 are movably connected by levers (not shown) and another device to the frame of the wrapping machine 1, so that during operation they may be slightly spaced apart and pressed back together in a substantially horizontal plane. The flaps 11 are also rotatable between two different positions, the open position shown at the top of FIG. 2 and the closed or working position shown at the bottom of FIG. 2. This movement is performed by levers (not shown) which are attached The fastening of the two sealing jaws 17 and the flaps 11 and their drive while the machine is running are known procedures which need not be described in detail and which have already been described, for example, in EP 91 712.

Jak již bylo dříve uvedeno, je každá chlopeň 11 tvořena střední stěnou 14 a dvěma koncovými částmi 15, jejichž pracovní povrchy, přivrácené k trubici 2 obalového materiálu jsou uloženy v podstatě kolmo na sebe, přičemž vždy dvě vzájemně se stýkající chlopně 11 vytvářejí prostor se čtyřmi stěnami pro trubici 7 obalového materiálu, jejíž obvod v podstatě odpovídá obvodu čtyřstěnného prostoru. Při uložení chlopní 11 do pracovní polohy, dotýkají se koncové plochy 19 koncových částí 15 tak, že rozměr čtyřsténného prostoru, vytvořený chlopněmi 11 pro trubici 2 obalového materiálu, je přesně definován. Koncové plochy 19 jsouAs previously mentioned, each flap 11 is formed by a central wall 14 and two end portions 15, the working surfaces of which face the packaging material tube 2 are substantially perpendicular to each other, each of the two flap 11 forming a space with four walls for the packaging material tube 7, the circumference of which essentially corresponds to the circumference of the tetrahedral space. When the flaps 11 are placed in the working position, the end surfaces 19 of the end portions 15 touch so that the dimension of the tetrahedral space formed by the flaps 11 for the packaging material tube 2 is precisely defined. The end faces 19 are

-3CZ 279925 B6 tvořeny v horní části chlopní 11 plochými oblastmi a na druhé straně vytvářejí dotýkající se výstupky 20 a vybrání 21, střídavě uložené tak, že jedna koncová část 15 chlopně 11 má výstupek 20 nad nálitkem 18 a vybrání 21 pod ním, zatímco druhá chlopeň 11 je tvarována obráceně. Vzhledem k tomu, že chlopně 11 jsou totožné, budou se výstupky 20 a vybrání 21 při styku chlopní 11 v pracovní poloze těsně dotýkat, takže koncové plochy 19 budou na sebe naléhat. Na svém zevním konci jsou výstupky 20 opatřeny skosením 22, které snižuje odpor při prvním styku koncové části 15 s vnější stěnou trubice 7 obalového materiálu.279925 B6 formed by flat areas at the top of the flaps 11 and on the other side forming abutting projections 20 and recesses 21 alternately positioned such that one end portion 15 of the tab 11 has a projection 20 above the boss 18 and recesses 21 below it. the flap 11 is inverted. Since the flaps 11 are identical, the protrusions 20 and recesses 21 will be in close contact with the flaps 11 in the operative position, so that the end surfaces 19 abut against each other. At their outer end, the projections 20 are provided with a bevel 22 which reduces the resistance when the end portion 15 first contacts the outer wall of the packaging material tube 7.

V případě, že je tvarovací zařízení podle vynálezu užito ve shora popsaném obalovém stroji, dojde nejprve k tomu, že pomocí dvou spolupracujících párů chlopní 11 je trubice 7 obalového materiálu nejprve vedena k hornímu páru zatavovacích čelistí 17, jak je znázorněno na obr. 2, takže obalový materiál je místně stlačen v příčné, poměrně úzké oblasti, přičemž se termoplastická vrstva laminátu 2 zataví teplem za vzniku kapalinotěsného sváru. Při stisknutí zatavovacích čelistí 17 jsou chlopně 11 uloženy v otevřené poloze, to znamená, že jsou skloněny poněkud směrem ven a nedostávají se do přímého styku s trubicí 7 obalového materiálu v okamžiku, kdy jsou zatavovací čelisti 17 v pracovní poloze. Z polohy, znázorněné v horní části obr. 2, se potom chlopně 11 postupně pohybují pomocí nálitku 18 směrem k sobě za otáčivého pohybu kolem krátkých hřídelů £6, takže zevní části koncových ploch 19., tj. skosení 22 výstupků 20, se dostanou do styku s vnější částí trubice 7 obalového materiálu. Při dalším uzavírání chlopní 11 a při současném pohybu zatavovacích čelistí 17 do polohy, znázorněné ve spodní části obr. 2, bude trubice 7 obalového materiálu pomocí výstupků 20 a postupně rovnoběžných povrchů koncových částí 15 stlačována a přetvářena na pravoúhlý průřez při těsném styku pracovních povrchů koncových částí 15 a středních stěn 14. Vzhledem k tomu, že spolu spolupracují výstupky 20. a vybrání 21, nedochází ke vzniku žádné přímé linie styku mezi koncovými částmi 15, takže současně nedochází k riziku sevření části trubice 7 obalového materiálu a jejímu možnému poškození mezi koncovými plochami 19, což dříve tvořilo hlavní problém. Vzhledem k tomu, že koncové plochy 19 podle vynálezu jsou provedeny jako vlnité a mimoto jsou opatřeny skosením 22, může být obalový laminát 2. snadno přiváděn do své polohy při pracovním pohybu chlopní 11 a praktickými zkouškami bylo prokázáno, že je možno zcela vyloučit tímto způsobem poškození trubice 7 sevřením. Jakmile zatavovací čelisti 17 dosáhnou polohy, znázorněné ve spodní části obr. 2, je zatavení příčné oblasti trubice 7 obalového materiálu ukončeno a zatavovací čelisti 17 jsou od sebe opět oddáleny, přičemž chlopně 11 se také vrací do poněkud otevřené polohy, znázorněné v horní části obr. 2. Tímto způsobem zatavovací čelisti 17 a s nimi spojené chlopně 11 postupně zpracovávají trubici 7_, která je dělena příčnými sváry na oddělená, stále však související balení pravoúhlého průřezu. Následující zpracování příčných svárů a dalších hran a rohů vytváří výsledný produkt ve formě rovnoběžnostěnu známého typu. Konstrukcí koncových ploch 19 chlopní 11 s výstupky 20 a vybráními 21 je možno vyloučit ploché, paralelní povrchy, které dříve byly příčinou sevření trubice 7 obalového materiálu s jejím poškozením, ztrátou kapalinotěsnosti a popřípadě také sterility vnitřního obsahu jednotlivých balení. Nový typ chlopně 11 podle vynálezu je možno snadno vyrobit a je možno jej bez obtíží využít v již existujících balicíchWhen the molding device according to the invention is used in the packaging machine described above, first, by means of two cooperating pairs of flaps 11, the packaging material tube 7 is first guided to the upper pair of sealing jaws 17, as shown in Fig. 2, such that the packaging material is locally compressed in a transverse, relatively narrow region, whereby the thermoplastic layer of the laminate 2 is heat sealed to form a liquid-tight weld. When the sealing jaws 17 are pressed, the flaps 11 are stored in the open position, i.e. they are inclined somewhat outwardly and do not come into direct contact with the packaging material tube 7 when the sealing jaws 17 are in the working position. From the position shown in the upper part of FIG. 2, the flaps 11 are then gradually moved by the boss 18 towards each other while rotating about the short shafts 66 so that the outer portions of the end surfaces 19, i.e. the bevel 22 of the protrusions 20, reach contacting the outer portion of the packaging material tube 7. Upon further closing the flaps 11 while moving the sealing jaws 17 to the position shown at the bottom of FIG. 2, the packaging material tube 7 will be compressed and deformed to a rectangular cross-section by close engagement of the working surfaces of the end portions by means of projections 20 and successively parallel surfaces. Since the projections 20 and the recesses 21 cooperate with each other, there is no direct line of contact between the end portions 15, so that there is no risk of pinching part of the packaging material tube 7 and possibly damaging it between the end portions. 19, which previously formed a major problem. Since the end surfaces 19 according to the invention are designed to be corrugated and furthermore provided with a chamfer 22, the packaging laminate 2 can be easily brought into position during the operation movement of the flaps 11 and has been proven by practical tests that damage to the tube 7 by clamping. Once the sealing jaws 17 have reached the position shown at the bottom of FIG. 2, the sealing of the transverse region of the packaging material tube 7 is complete and the sealing jaws 17 are spaced apart again, the flaps 11 also returning to the somewhat open position shown at the top. 2. In this way, the sealing jaws 17 and the associated flaps 11 gradually process a tube 7 which is divided by transverse welds into separate, but still related, packages of rectangular cross-section. Subsequent processing of the transverse welds and other edges and corners produces the resulting product in the form of a parallelepiped of known type. By constructing the end surfaces 19 of the flaps 11 with the protrusions 20 and the recesses 21, it is possible to eliminate the flat, parallel surfaces which previously caused clamping of the packaging material tube 7 with its damage, loss of liquid tightness and possibly sterility of the inner contents of individual packages. The novel type of flap 11 according to the invention is easy to manufacture and can be used without difficulty in existing packaging

-4CZ 279925 B6 strojích, čímž je možno natrvalo vyřešit problémy s deformací trubicovitého obalového materiálu.This makes it possible to permanently solve the deformation problems of the tubular packaging material.

Vynález byl sice popsán v souvislosti s výhodným provedením, je však možno navrhnout ještě řadu modifikací.While the invention has been described in connection with a preferred embodiment, many modifications may be made.
